Overview

Introducing the Cat® 789D Autonomous Water Truck

An industry first, the Cat® 789D Autonomous Water Truck is a complete solution that not only automates the truck, but also automates the delivery of the water — optimizing the complete haul road watering process. Autonomous water trucks help dust suppression on site and enhance productivity by enabling mine operations to digitally track water consumption and reduce waste.

The Cat Autonomous Water Truck includes the full support of the Cat dealer and parts network. Combining an automated water delivery system with an autonomous truck, powered by MineStar, creates a truly automated solution that takes haul road watering safety and efficiency to a new level.

Benefits

Enhance Safety and Productivity at Your Mine Site

Know where and when to water – lower dust levels, increase visibility, maintain haul road safety.

Autonomous Water Delivery with Cat® MineStar™ Command

Provides consistent watering to match production targets.

Reduces Environmental Impact

Knowing precisely how much to water can help you save water.

Note (1) Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate. Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate.
Note (2) The Auto Mode setting controls water coverage and automatically adjusts to the number of spray heads being used — independent of ground speed. This is an exclusive feature designed into the Cat WDS software to help water more efficiently. Water flow is continually adjusted during operation to conserve water and achieve desired coverage and flow rate.
